属性值

DataKey

数据绑定控件中所选记录的数据键值。The data-key value for the selected record in a data-bound control.

注解

DataKey属性不同于数据绑定控件所进行的默认选择,因为所选的项可在分页之间保持不变,并且项可能不在当前页上。The DataKey property differs from the default selection made by the data-bound control because the item selected can be persisted across paging and the item may not be on the current page.
